From -A/2 to A/2 the total displacemnt would be = > A Hence time would be T/4 +T/4 = T/2 where T is time priod of the pendulum.
Gravity force i given as = product of the mass of a body with the acceleration g = 9.8 m/s^2 Hence it only depends upon the mass of the object irrespective of irregular path or distance it tends to...
Velocity would be => v = 2*pi*r/T r is the length of the semi mjor or minor axis. Hence close to the earth r would be more and velocity would be high than at the farthest distance.
Here Force is acting on mass horizontally and friction would act vertically hence Friction force would be=> f = uF Hence to hold a mass M, uF = Mg u = Mg/F
Equation of states uses the ideal gas eqns. and describe and governs according to the physical conditions of parameters provided. And thus works accordingly to the laws like Boyles law , charles law...
From first law of thermodynamics, Q = U + W U =0 as internal energy is zero for closed path. Therefore, Q = W = 0 forc closed path.
Equation of SHM is: x = Asin(wt + $) w = 2pi/f = > 2pi/600 = > pi/300 and phae = > $ = pi/6 Hence eqn. becomes, x = 0.01sin(pit/300 + pi/6)

The answer is 3kmph because Time is width / 5sinx15/60 =1/5sinxSinx= 4/5. Cosx=3/5 so Velocity of river is 5 cosx = 3
The formula of KE = p^2/2m where p is momentum. Here p is constant do KE is inversely proportional to mass There ratio of KE is16:4 = 4:1
We know that a meter bridge follows the Wheatstone Bridge principle that is P/Q=R/S For the first part is both R and X are doubled and interchanged then,2X/2R is X/R. So the new balance point will be ...
For 8 total steps it takes 8 seconds, and moves in total 2 steps forward (2 m) Therfore, 3*2 m = 6 m At 3rd cycle Time Elapsed 24 s After walking 5 m forward, he takes 5 s more. It becomes 11 m. Time ...
From -dT/dt = k(T – T0) dT = – k(T – T0)dt Integerating both sides with appropriate limits, log(T- T0) = -Kt (-2.306/K)log2t = K = -2.303*log2/300 we get t = 10 minutes.
